Recovery after a comminuted patella fracture with tension band wiring and screws can take many months because the knee muscles, ligaments, and joint movement need time to regain strength and stability after surgery. Reaching around 120 degrees of bending at 5 months is generally a positive sign, but difficulty running may still happen due to weakness of the thigh muscles, stiffness, reduced balance, or fear of putting pressure on the knee. Physiotherapy is usually very important at this stage. Exercises focusing on quadriceps strengthening, hamstring stretches, balance training, stationary cycling, step exercises, and gradual weight-bearing activities may help improve knee control and strength over time. Running is often introduced slowly, only after muscle strength and knee stability improve adequately. Avoid sudden jumping, twisting, or heavy impact activities too early because they may strain the healing knee. Good nutrition, protein intake, and regular supervised rehabilitation can support recovery further. Please consult your orthopaedic surgeon or physiotherapist if swelling, instability, severe pain, or locking of the knee continues, as follow-up imaging or adjustment in rehabilitation may be needed.
