Overview
Patellofemoral Pain Syndrome (PFPS) — colloquially called 'Runner's Knee' — is characterised by pain at or around the front of the knee (kneecap region) that is aggravated by activities loading the patellofemoral joint: running, squatting, climbing stairs, prolonged sitting with bent knees (the 'theatre sign'), and kneeling. It is the most common running injury in women and the most prevalent knee complaint in adolescent athletes. PFPS is fundamentally a mismatch problem: the patella is pulled laterally out of its optimal tracking groove by weakness in the inner quadriceps (VMO), tight lateral retinaculum, and poor hip control — causing focal cartilage stress at the lateral facet of the patella. Importantly, PFPS is distinct from Knee Osteoarthritis (OA), ACL tears, and Meniscus tears — it is a soft tissue and biomechanical problem that responds exceptionally well to physiotherapy when correctly diagnosed and managed. At Curis 360 Physiotherapy's Banashankari, Jayanagar, and Vasanthapura clinics, Dr. Ponkhi Sharma PT and her team manage PFPS with a hip-knee-foot integrated approach, resolving the majority of cases within 6–8 weeks.
Common Symptoms
- Diffuse aching or sharp pain around or behind the kneecap during or after running, squatting, or stair climbing.
- Pain after prolonged sitting with the knee bent — the 'theatre sign' or 'movie-goer's knee'.
- A sensation of grinding or crackling (crepitus) behind the kneecap during knee flexion and extension.
- Giving way of the knee on loading — not true instability but apprehension about the knee.
- Worsening pain when walking or running downhill or down stairs (greater patellofemoral compression).
- Swelling in and around the kneecap, particularly after prolonged activity.
- Pain on pressing firmly above, below, or on the medial or lateral edges of the kneecap.
Primary Causes
- Weakness of the vastus medialis oblique (VMO — the inner quadriceps teardrop muscle) that fails to centre the patella in its groove.
- Hip abductor and external rotator weakness — insufficient hip control causes femoral adduction and internal rotation, increasing patellofemoral compression.
- Tight lateral retinaculum and iliotibial band — pull the patella laterally, causing malalignment.
- Overpronated feet (flat arches) — increase tibial internal rotation and patellofemoral stress.
- Training load errors — sudden volume increases in running, cycling, or gym-based squatting.
- High-heel wearing — shortens the gastrocnemius, increasing compressive forces at the patellofemoral joint during gait.
- Post-adolescent growth spurts — rapid femoral growth without corresponding quadriceps adaptation increases patellar stress.
1. Why PFPS is Mismanaged — The VMO Myth and the Hip Truth
For decades, PFPS management focused almost exclusively on VMO (vastus medialis oblique) strengthening — the premise being that selective VMO activation via terminal knee extension and short arc quads exercises would pull the patella medially back into its groove. While VMO strengthening remains valuable, modern evidence has shifted the primary therapeutic emphasis proximal — to the hip. A landmark systematic review (Prins & van der Wurff, 2009) and subsequent RCTs consistently demonstrate that a combined hip and knee programme outperforms knee-only treatment for PFPS, with hip-dominant programmes showing the fastest pain reduction.
At Curis 360's Banashankari and Jayanagar clinics, our PFPS assessment always includes a hip abductor and external rotator strength test — and the results are consistently revealing. The majority of our PFPS patients, particularly women, demonstrate a 25–40% hip abductor strength deficit on the symptomatic side. Strengthening these hip muscles reduces the dynamic valgus collapse (knee falling inward) at midstance and reduces patellofemoral compression forces by up to 22%.
2. Phase 1 — McConnell Taping & Immediate Pain Relief (Week 1–2)
The McConnell patellar taping technique — applying rigid sports tape to draw the patella medially within its groove — produces immediate, clinically significant pain relief in PFPS patients, allowing them to exercise through a greater pain-free range from the very first session. The Physiotherapy Evidence Database (PEDro) grades McConnell taping as Level 1 evidence for PFPS pain reduction. At Curis 360 Jayanagar and Vasanthapura clinics, we apply McConnell tape at the start of each session, teach patients to self-tape at home, and transition to patellar tracking braces (soft neoprene knee sleeves with patellar cutout and lateral buttress) for daily activity.
During the first two weeks, we also use soft tissue therapy to the lateral retinaculum and IT band to reduce the lateral tethering pull on the patella. Isometric quadriceps exercises in the pain-free range (leg press at 10° flexion, quad sets) begin immediately to reverse the rapid quadriceps inhibition that occurs with knee pain. All exercises are performed within a range that keeps patellofemoral joint reaction forces manageable — avoiding full squat depth and deep knee flexion until strength is adequate to protect the joint.
3. Phase 2 — Integrated Hip-Knee Strengthening Programme
Phase 2 runs from weeks 2–6 and is the core therapeutic intervention. Our programme at Curis 360 Banashankari and Vasanthapura clinics is fully integrated — all exercises simultaneously challenge hip control AND knee quadriceps — because this closely mimics the demands of real sport and daily life. Key exercises include: (a) Step-down exercise — standing on a step, lowering the opposite foot to the floor slowly while maintaining strict knee alignment over the second toe (the most functionally specific PFPS exercise); (b) Lateral band walk with squat — resistance band around ankles, perform lateral steps combined with squat depth; (c) Single-leg mini-squat to 60° — progressing from double-leg to single-leg as strength allows; (d) Hip thrust with lateral band — glute bridge with resistance band around knees to activate hip external rotators simultaneously; (e) Step-up and step-down on a 20 cm step.
Quadriceps strengthening is progressed from short arc quads (0–30°) and terminal knee extension to half-squats (0–60°) and leg press (limited to 60°) as pain permits. We avoid full deep squats until Phase 3. Running is permitted as long as it can be completed with pain below 3/10 and there is no pain spike lasting more than 24 hours afterwards.
4. Phase 3 — Functional Training & Return to Sport
Phase 3 (weeks 6–10) introduces sport-specific loading and plyometrics. The single-leg squat is the benchmark movement — the patient should be able to perform 3 sets of 15 single-leg squats to 60° with perfect knee alignment (no valgus collapse, no trunk sway) before progressing to jumping and cutting movements. We introduce double-leg squat jumps → single-leg landing → bounding → sport-specific change-of-direction drills in a progressive sequence.
For athletes returning to football, basketball, or badminton in Bangalore, we also perform a sport-specific return-to-training programme with graduated exposure to the demands of their sport — 50% training intensity for 1 week, then 75%, then full intensity — with pain monitoring throughout. Return is cleared when the single-leg squat shows <10% symmetry deficit, hop testing LSI >90%, and pain consistently below 2/10 during sport-simulated activity.
5. Foot Orthotics, Footwear, and the Role of Pronation in PFPS
Excessive foot pronation is a significant biomechanical contributor to PFPS in a subset of patients — approximately 30–40% of our PFPS cases at Curis 360 Banashankari and Jayanagar clinics have a clinically significant flat foot or excessive dynamic pronation that drives tibial internal rotation and patellofemoral compression. For these patients, custom or prefabricated foot orthotics are prescribed as an adjunct to exercise.
A Cochrane review (Collins et al., 2018) found that combining foot orthotics with exercise therapy produces significantly faster short-term pain reduction than exercise alone in PFPS patients with pronation. Our orthotics are semi-rigid, 3/4 length with a medial arch support and rearfoot post. We also advise these patients on footwear: stability running shoes with medial post (Brooks Adrenaline GTS, ASICS Kayano) for running; solid arch-support footwear for daily use; avoidance of flat, unsupportive footwear and high heels.
Frequently Asked Questions
How is runner's knee (PFPS) different from Knee Osteoarthritis?
PFPS is a soft tissue and biomechanical problem affecting the patellofemoral joint in younger, active people. It does not involve cartilage destruction or bone changes and does not progress to OA. Knee Osteoarthritis involves degeneration of the articular cartilage in the tibiofemoral (main) compartment, typically in older adults. The pain patterns differ: PFPS is anterior kneecap pain in young active people; OA is joint-line pain in older adults with stiffness and loss of range. Different conditions, different treatments.
Can I squat if I have PFPS?
Modified squatting (to 60° depth, with feet wider and toes turned out slightly) is prescribed as a rehabilitation exercise for PFPS — not avoided. The goal is to progressively increase patellofemoral loading capacity through controlled exercise, not to avoid the joint. Full-depth squatting is introduced only when quadriceps strength and hip control are sufficient to protect the joint.
Will physiotherapy cure PFPS permanently?
Yes — PFPS responds very well to physiotherapy, with resolution rates of 75–90% reported in high-quality trials. The key is addressing both the local (VMO, lateral retinaculum) and proximal (hip abductor, external rotators) contributors, combined with permanent integration of hip and knee strengthening into the patient's training routine. Patients who discontinue all exercise after symptom resolution have higher relapse rates.
Can I get PFPS physiotherapy at home in Bangalore?
Yes. Curis 360 offers home physiotherapy for PFPS across all of Bengaluru — Banashankari, Jayanagar, Vasanthapura, and across the city. Our physiotherapists bring McConnell tape, resistance bands, and a step platform and deliver the full integrated hip-knee programme at your home.
